Korokke are mashed potato cakes that are coated with panko and deep-fried. Korokke is a food people of all ages love in Japan. With a crispy crust and creamy, savory interior, they are delicious served as a snack, appetizer, or part of a meal.

It’s said that korokke originated from French croquette or Dutch kroket. It became a widespread Western-style food in Japan in the early 1900s and evolved to suit more Japanese tastes. This recipe is for a basic type of korokke, but there are many variations. Curry korokke are spiced with curry powder, kabocha or pumpkin korokke use the veggie as a filling, and even nikujaga korokke using mashed leftover nikujaga, a meat and potato stew.

Try it with organic beef, carrots, or shiitake mushrooms. Enjoy korokke with the sauce of your choice—tonkatsu sauce, Worcestershire sauce, ketchup, or just as is. Since the recipe takes some time to make, consider making extra to freeze and have them anytime you want.

  2. Put a medium pot of water on to boil. Boil the peeled, quartered potatoes until softened. Test with a skewer―they're ready when the skewer goes through easily.

  3. Drain the cooked potatoes in a colander and return to the pot. Mash the potatoes while they are hot.

  4. Heat a little oil in a medium skillet and sauté the beef and onion until cooked through.

  5. Combine the mashed potatoes with the cooked beef and onion in a mixing bowl. Stir together, season with salt and pepper, and let the mixture cool.

  6. Form the cooled mixture with your hands into flattened, oval-shaped patties.

  7. Add the oil to a heavy-bottomed, deep pot and heat over medium-high heat to 350 F.

  8. Add the flour to one shallow bowl, the beaten egg to another, and the panko to another. Coat each potato patty with flour. Dip in beaten egg and let any excess drip off. Lastly, coat with the panko.

  9. Deep-fry, working in batches if needed, until deep golden brown and crispy, flipping as needed. Don't overcrowd the pot. Drain on a cooling rack or paper towels and repeat with the remaining korokke.

Tips

  • Don't make the korokke too big, or they won't hold together well while frying.
  • Don't fry too many at a time or the temperature of the oil will drop and make the korokke oily.
  • Russet potatoes are the better choice of potatoes for this type of dish. They are a good baking potato but also great for frying and making french fries.

How to Store and Freeze

  • Potato korokke can be frozen, so go ahead and double the recipe to have some ready for later. Prepare as instructed, but do not deep fry them. Instead, wrap the uncooked korokke in plastic wrap, and then place them in a freezer bag. They will last for up to a month in the freezer. When ready to eat, there's no need to defrost, just go ahead and deep-fry them.
